The Steyr TMP (Tactical Machine Pistol) is a select-fire 9x19mm Parabellum caliber machine pistol manufactured by the Austrian company, Steyr Mannlicher. It is renowned for its controllability, allowing a shooter to accurately fire the weapon in bursts of more than 10-15 rounds, instead of the typical two or three round bursts that other submachine guns are limited to. Magazines come in 15/30 round detachable box types. A suppressor can be also fitted. The Steyr SPP is the civilian variant of the TMP which has no foregrip and is capable of semi-automatic fire only.

In 2001, Steyr sold the design to Brügger & Thomet who developed it into the Brügger & Thomet MP9.

The Steyr SPP (Special Purpose Pistol) is a semi-automatic variant of the TMP. The TMP barrel and barrel jacket lengths were increased slightly so there is a greater length of protruding jacket and barrel. The forward tactical handle was removed and a small spur installed instead.

The SPP is believed to have been created in order to fulfill the pistol portion of the XVII Land Warrior objective handheld personal defense weapon. It is somewhat large for a pistol and is constructed mainly from synthetic materials.
